Jeesh - its not that bad. Instrument, night, para drop, tow, aero's ratings or endorsements are forever (you just have to do some to keep it CURRENT). You don't have to re-do any of these every time you change an aircraft type. (exception of course SEIR to MEIR)
Aircraft type ratings can be from 3 circuits to hours depending on pilot ability and / or greedy institutions/instructors.
